How quickly can your body absorb estrogen from soy?

The body can absorb estrogen from soy relatively quickly, with studies indicating that isoflavones, the phytoestrogens found in soy, can be detected in the bloodstream within a few hours after consumption. However, the extent of absorption and the physiological effects can vary based on individual factors such as metabolism, gut microbiota, and overall diet. Generally, peak levels of isoflavones in the blood occur between 1 to 6 hours after intake.
